Fig. 2 is a sectional (ltilllHlllg tho sumo.

Roferring. now more particularly to the drawings wherein like numerals of referllltt designate similar ports in each of the figuresthe numeral trefers to a draft nozzle which is substantially cylindrical in shape and which is screwed onto the nipple T. whirh projects from the collar 7 and is onto the pipe sevtion 8. Within this nozzle, and integral withtho nipple, is the stem 8', forming aiportion ofthe fuel passageway. This stem ulines 'n'itli on internal passageway of nipple T and extends toward the nose of the nozzle 1 and in length is about onehzdf the length of said nozzle. The nose 9 :11. now/Ale i5 is rodurod and tapers towurd its end and is oll'sot relative to the bodv of slltl nozzle so-us lo form an abrupt shoulder l'll. runner-ting sold nose 9 and the body of the nozzle.

Tho numeral It refers to'a, sleevo which [its over the tree 0nd of; stem 8', so as to form-a slip joint and this sleeve is elongated in'lo'a who 1:, which ulines with stem 8 and extends within the nose 9 to the end thereof and is provided with a plurality of radiating inner side of disrhargo nose 9 and hold the lulu' l2 rumored relatively to the nozzle, the stem h" and tube 12-, together with the fuel. pussugrt'u'u-jy lhrouh the draft nozzlefi.

whit-h is interposed between sleve ll and nipple -T annl which forms mreqilient cushlll'lw; 12 extended tfllll'lllll'ely throu 11 110569,

hut which permits said tube to hunk thus enlarging the. passageway between .lllt disvhul'go mid of said tube and said noz- Zlt'. t3.

'l'hodrnfl of stouln or air is admitted into tum/.10 6 through fol're'nine 15 and is driven side olevution lit the blow-hack cup used in integral the|'e \\'-ith. This eolluris screwed arms 13 whose free ends rest againstthe' 'l'lw-nulnvral l-l r0 ers to u coil spring ion for said sleeve. and normally holds'thel through the nose 9, passing around the nozzle of tube 12 and by reason of the taper or choke of nose 9, creating a suction through the fuel passageway. The fuel is admitted under ressure from a suitable fuel reservoir not shown) throu h pipe 16, which is controlled by a suitab e gate valve 17, and passes throu h tubes 8 and 12 and is forced through t e passageway 18 of the furnace wall 19 into the mixing chamber 20 in which it is thoroughly atortlized and mixed with the steam or air in said mixing chamber, and ignited and from which it is driven, by the force ofusaid draft against the wall 21, of the furnace. G

The passageway 18, and the mixing chamber 20 taper from their receiving to their discharge ends and aline with each other as well as with the burner, as shown in Fig. 3. The mixing chamber 20 is rovided with an air inlet 32, underneath, t rough which additional air may be supplied and the tapering contour of this chamber is such as to create a suction therethrough and cause a com lete mixture of the air and fuel therein.

T e numeral 22 refers to an auxiliary pipe which communicates with the interior of the furnace and extends through the wall 19 thereof and eomu'mnicates, also, with the fuel passageway and is provided for the purpose of introducin hot gases from the furnace into the foe passa eway -which heats and mixes with the fue and thus assists in the atomization of said fuel. This auxiliary pipe 22 is controlled by a gate valve 23 by means of which the passa of the gases therethrough may be regu ated, and when the burner is in operation this valve is partly closed so that only a limited su 1y of gas enters the fuel pi e.

e nose, or discharge en 9, -of the burner is completely surrounded with a funnel shaped hood 24. which is supported thereon by means of the ring 25, screwed onto said discharge end 9, and radiating arms 26 extending from said ring and secured to said hood. The shoulder 10, of nozzle 6 is provided 'with a pluralit of openings 27, through which jets of t e atomizing fluid are driven within the surroundin hood 24 thereby creating a suction throng said hood and around the nose 9, which draws in an additional sup ly of air which is mixed with the fuel as it eaves the mouth of the nozzle.

The numeral 27' refers toa blowhack cup whose interior conforms to the rounded end of nose 9 and which is designed to be placed thereover when it is desired to clean the burner or unstop either of theinlct pipes leading thereto. The bottom of this cup carries a projecting cross 28 which en ages against the free end of tube 12 and orces the some back, depressing the coil spring 14,

while the cup proper rests against the nose 9. In case it is desired to cleanse the burner of any obstructions which may have collected in either passage way thereof the plug 29 is removed from feed pi e 16 and when the nozzle is closed by cu 2 the atomizing fluid is driven through t e fuel passageway and escapes through the opening in the feed pipe left by the removal of plug 29. Both ate valves 17 and 23, should be closed when it is desired to thus cleanse the burner. When either of the ipes, 16 or 22, becomes clogged, the gate va ve of said clogged pipe may be opened, and the other gate valve closed and plug 29 screwed into place. The cup 27' is then applied over the mouth of nozzle 6 and the atoinizing fluid will be driven through the clogged pipe, thus unclogging the same. The bottom of cup 27 is rovided with a socket 30 in which a suitablh rod or bar may be placed and secured by set screw 31, and a handle for said cup thus provided. The cup may then be applied to the burner nozzle and the burner pi es cleansed, as above described.
